A few key players could be returning from injuries this weekend, but fantasy football owners should be careful about which ones they trust for crucial Week 13 matchups.

It sounds like Darren McFadden (ankle) and DeMarco Murray (foot) both have a chance to return Sunday after multi-week absences. However, on top of re-injury and workload concerns, there are added risks to starting these two. The forecast in Oakland calls for sloppy conditions, which could give the Raiders pause about playing McFadden at all; Dallas doesn't play until Sunday night, so owners may not know his status until late.

Meanwhile, the Packers' Greg Jennings (groin) and the Steelers' Antonio Brown (ankle) are expected to return Sunday, but both are risky plays after long layoffs. Brown comes with the added drawback of having Charlie Batch at quarterback with Ben Roethlisberger (ribs) being ruled out again.

Add in long shots to return such as LeSean McCoy (concussion) and Percy Harvin (ankle), with the uncertainty around Matt Forte (ankle), Danny Amendola (foot) and Jonathan Stewart (ankles), and fantasy owners will have some tough game-time decisions to make. Don't worry, though. The Fantasy Source experts will help make those calls once again during our live fantasy football chat from 10 a.m. to 1 p.m. ET on Sunday, available to Fantasy Source members.

THE DECIDER

Start 'em:

Pierre Garcon, Redskins. Keeping up the "aren't-you-glad-you-waited-on-me" theme, Garcon showed his bum foot didn't affect him in a busy, explosive day against Dallas that his fantasy owners expected for most of the season. Now that you've seen Garcon is doing what he can do again, roll with him in prime time against the Giants.

Three more: Don't hesitate to start Green Bay's Greg Jennings if he's deemed healthy enough to go against Minnesota, because the Packers' offense could use him right away; the Dolphins have made better use of Davone Bess to help Ryan Tannehill, and should rack up some garbage production against New England; if Cleveland's Brandon Weeden plays at Oakland, be sure to have Josh Gordon in your lineup.

Sit 'em:

Malcom Floyd and Danario Alexander, Chargers. Floyd is hurt by Alexander's production and good chemistry with Philip Rivers, and both are hurt by facing a Bengals' defense that has given up fewer than 500 yards to wideouts and only three TDs to wide receivers over the past five weeks.

Three more: The Ravens' Torrey Smith has fought through some tough matchups to produce well of late, but the Steelers weren't one of them in Week 11; the Chiefs' Dwayne Bowe has little appeal with his QB situation and a date with Carolina's secondary; the 49ers' Michael Crabtree has had his numbers curbed with Colin Kaepernick as the quarterback.

RANKINGS ANALYSIS

Quarterbacks

Stud: Colin Kaepernick, 49ers (No. 4). How is this possible? After back-to-back 20-point outings, it's hard to second guess Jim Harbaugh's decision to start Kaepernick. While the jury is out on whether Alex Smith is the better bet for a Super Bowl run, there's no question Kaepernick is the better fantasy quarterback. Start him against the Rams.

Sleeper: Jake Locker, Titans (No. 21). Houston's defense is short two impact linebackers with the loss of Brooks Reed, and cornerback Johnathan Joseph is still nursing a hamstring injury. The Texans allowed 819 passing yards the last two weeks. Tennessee's offense is unpredictable, but Locker could be next in line for a prolific day.

Go For It?: Andrew Luck, Colts (No. 15). It might seem incredulous to rank Luck behind Buffalo's Ryan Fitzpatrick (No. 13) and Jacksonville's Chad Henne (No. 14), but Luck struggled last week. Plus, the Lions are better than they seem against pass-happy teams. Luck's struggles on the road also are noted, but he still gets 20 points. Play through the matchup.

Pierre Garcon, WR, Redskins. Garcon reappeared with 15.3 fantasy points against the Cowboys, his best production since Week 1 against the Saints. His foot problem seems to have alleviated, and he is ready for a prime matchup against the Giants, who are allowing the fifth-most fantasy points to opposing wide receivers. Garcon is worth starting as a WR2 in fantasy leagues.

Lawrence Tynes, K, Giants. Tynes has been the highest-scoring kicker this season and the Redskins are allowing the seventh-most fantasy points to opposing kickers. This is a no-brainer.

4-Star Players

Robert Griffin III, QB, Redskins. After emerging from a Week 10 bye Griffin has averaged 38.8 fantasy points per game the past two weeks. And in the first matchup with the Giants this season, Griffin put up 27.2 fantasy points. Washington needs this game in order to have any chance of contending for a playoff spot, so look for Griffin to let loose in a potential shootout with Eli Manning.

Eli Manning, QB, Giants. Manning looked rejuvenated after the Giants' bye week as he plundered the Packers for 29.2 fantasy points in a 38-10 rout. It was his biggest fantasy output since Week 2 against the Bucs and bodes well heading into a matchup with the Redskins, who are allowing the third-most fantasy points to QBs this season. The only thing keeping Manning from being a five-star player, though, is his poor history against the Redskins. In 16 games against them, he has thrown 13 TD passes and 15 interceptions.
